GEORGE G. SCIIROEDER, OF WASHINGTON, DISTRICT OF COLUMBIA, ASSIGNOR TOINDUSTRIAL ALCOHOL HEAT AND LIGHT COMPANY, A CORPORATION OF SOUTHDAKOTA.

DENATURED-ALCOHOL HEATER.

Specification of Letters Patent.

Patented Sept. 17, 1907.

To all whom it may concern:

Be it known that I, GEORGE G. SoHRonDnn, a citizen of the United States,residing at Washington, in the District of Columbia, have inventedcertain new and useful Improvements in Denatured-Alcohol Heaters, ofwhich the following is a specification.

This invention has relation to denatured alcohol heaters, and itconsists in the novel construction and arrangement of its parts ashereinafter shown and described.

The object of the invention is to provide an individual detached heaterof the character as indicated; one that may be readily moved from placeto place without disconnecting couplings or other fuel feeding means. Atthe same time the heater is of simple construction and is of suchdimensions as to take up but little room when in operation.

The heater consists primarily of a drum mounted upon a base, with a fuelreservoir surrounding the upper portion of the drum. Fuel supply pipesconnect at their' upper ends with the said reservoir and pass into thedrum and down along the inner sides of the same and connect with thefuel burner which is located in the base. ySuitable valves beinginterposed between the supply tank and the heater, as will behereinafter explained.

The burner is of special construction, and is especially adapted forheating purposes and for converting the liquid fuel into gas and mixingthe same with air before the resultant mixture is consumed. It consistsof a pan into which the liquid is first introduced through a reducedpipe from one of the supply pipes for the purpose of starting the burneror heating the same to the desired temperature in order that the mainburner may automatically generate the gas and produce the mixture asbefore stated. The supply pipes connect with a vertically arrangedcylinder which is provided with a series of spray perforations arrangedin horizontal circular rows. A casing surrounds the said cylinder, andis composed of a series of meniscus sections joined together at theiredges, said sections increasing in diameter from the lower to the upper.The rows of spray perforations in the said cylinder are arranged at thelevels of the outer meeting edges of the said meniscus sections. Theupper portion of the said casing is spaced from the outer side of thecylinder, and its upper opening is covered with a foraminous material.An air mixing chamber is arranged above the casing and is provided witha Hat top which in turn is provided with peripheral openings.

In the accompanying drawingsz-Figure 1, is a perspective view of theheater. Fig. 2, is a vertical sectional view of the same. Fig. 3, is aperspective view of the burner detached, and: Fig. 4, is a vertical sectional view of the burner detached.

The heater comprises the drum 1, which is separably mounted upon thebase 2. The drum is surrounded by the fuel reservoir 3. The top of thedrum is provided with the draft escape 4. The fuel supply pipes 5, 5,connect at their upper ends with the fuel tank 3, and pass down alongthe inside of the drum and enter the base 2. Within the base 2, the saidfuel supply pipes 5, 5, come together and join with the vertical pipe 6,which is provided with a needle valve 7 The cylinder S is mounted uponthe upper end of the pipe 6, and is provided with a number ofperforations 9, arranged in horizontal rows. The upper end of the saidcylinder is closed. The starting pan 1.0 is located upon the pipe 6,below the cylinder 8, and the pipe 11 connects at its lower end with oneof the pipes 5, and terminates at its upper end above the pan 10. Saidpipe 11 is provided with a needle valve 12. The casing 13 surrounds thecylinder 8, and the top thereof is provided with a central outletopening. Said casing is composed of a number of meniscus sections joinedtogether at their edges. Said sections increasing in diameter from thelower to the upper, and having their inner edges in vertical alinement,and their outer edges in oblique alinement. The rows of perforations 9are located in the same horizontal level as the outer meeting edges ofthe said meniscus sections. The fiat topped mixing chamber 15 islocatedon top of the chamber 13, the bottom of said mixing chamber beingprovided with a collar fitting in the outlet opening of casing 13, saidmixing chamber resting on said casing. The

foraminous screen 14 is located within the collar of the mixing chamber15 and extends above the outlet opening of chamber 13. Said mixingchamber 15 is provided with peripheral fiame openings 1G and airadmission openings 17 From the foregoing description it is obvious thatwhen the denatured alcohol is led from the tank 3, down through thepipes 5, 5, and up through the pipe 1l into the starting pan 10, and isignited in the said pan, the heat from the flame will envelop the casing13, and will also enter the drum 1. This gasifies the fuel in the saidpipes 5, 5, and the tank 3, and when sufficiently gasiiied the valve 12is closed and the valve 7 is opened. The fuel gas will then pass up intothe cylinder 8 and spray through the perforations 9 into the cornersformed by the outer meeting edges of the meniscus sections of thecasing. Thus by being brought into direct contact with the hot metal,the particles of fuel become highly gasified and pass through theforaminous material 14, and enter the mixing chamber 15. In the saidchamber the fuel gas is mixed with air' which is admitted through theperforations 17, and the resultant mixture passes out through theperipheral perforations 1G, where the mixture is ignited. Thus theprocess of gasification is carried on by the main bur'ner after theparts have become suflciently hot.

Having described my invention, what I claim as new and desire to secureby Letters Patent is 1. A heater of the character' described comprisinga vaporizing chamber formed of meniscus sections joined at their edges,a perforated cylindrical member located within said vaporizing chamberand r'esting on the bottom thereof, means for supplying hydrocarbon tosaid member, and a mixing chamber resting on the top of said vapor'izingchamber and communicating therewith, said mixing chamber' being providedwith peripheral flame outlets.
